The Texas county that includes Houston will ask the state attorney general to investigate suing Mortgage Electronic Registration Systems Inc. over unpaid filing fees on behalf of all the counties in Texas, an official said.

“If this is something that affects county government all over the state, why isn’t the state attorney general pursuing it?” Harris County Judge Ed Emmett said in an interview today. Emmett is a member of the Harris County Commissioners Court and the highest elected official of the county.
